In the suffocating heat of a small desert town, a mysterious and painful affliction begins to spread in director Olivia Simon's unsettling psychological thriller. The film follows Maya, a guarded young woman who returns to her isolated hometown after years away, only to find her community gripped by a strange epidemic where emotional stress manifests as severe, unexplained blisters on the skin. As Maya reconnects with her ailing mother and a childhood friend now leading the local clinic, she is forced to confront the traumas she fled, discovering the blisters are not random but intimately tied to the town's long-buried secrets and collective guilt. Trapped by a growing quarantine, Maya must navigate a landscape of fear, paranoia, and hidden truths, where healing the physical symptoms means first exposing festering emotional wounds. This tense and atmospheric film masterfully blends body horror with deep human drama, creating a palpable sense of dread as the line between psychological and physical torment horrifyingly dissolves.
